ACE inhibitors High Blood Pressure
These work by making the walls of the arteries relax and widen. They are particularly effective in treating high blood pressure when used with a diuretic. In young people with high blood pressure they are often used on their own.
ACE stands for ‘ angiotensin converting enzyme ’. ACE inhibitors help to prevent an inactive substance in the blood called angiotensin I from converting into the very potent angiotensin II. Angiotensin II produces spasms and narrows the blood vessels.
Unwanted effects
Some people develop a persistent, dry, irritating cough. If this happens, you should tell your doctor about it.
In some rare cases, ACE inhibitors can cause a significant fall in blood pressure when the person takes his or her first dose.
When your doctor first prescribes the treatment, he or she will start you on a low dose and will regularly check your blood pressure. They will also check whether your kidneys are working well, by taking a blood test.
Some ACE inhibitors may cause skin rashes and, very occasionally, a major allergic reaction. If you think you have an allergy to these medicines, stop taking them and contact your doctor.
